Or do you claim that people who have not x amount of merit earned are automatically scammers and spammers who shouldn't be accepted into campaigns?
They're not. There are members with zero merits earned in other campaigns as well but no one has a problem with that since they're not flooding the forum with spam like Stake's signature campaign. Just go through any thread in the Gambling discussion board you'll be annoyed to see the threads are just filled with posts one after other from Stake's participants.
